Abstract
Ein Fahrzeugmotor (10, 50) beinhaltet: einen Zylinderkopf; ein Nockengehäuse (12), das an einer Oberseite des Zylinderkopfes befestigt ist; eine Nockenkappe (14, 52), die an einer Oberseite des Nockengehäuses befestigt ist; eine Nockenwelle (16), die drehbar zwischen dem Nockengehäuse (12) und der Nockenkappe (14, 52) gestützt ist, wobei die Nockenwelle (16) eine Nocke (18) stützt; einen Kipphebel (20), der dafür ausgelegt ist, durch die Nocke (18) geschoben zu werden; und ein Ventil (22), das dafür ausgelegt ist, dadurch betätigt zu werden, dass es durch den Kipphebel (20) geschoben wird; sowie eine Ölleitung (32, 60), die integral mit der Nockenkappe (14, 52) ausgebildet ist. Schmieröl wird durch die Ölleitung (32, 60) zu einem Kontaktpunkt zwischen der Nocke (18) und dem Kipphebel (20) geleitet.A vehicle engine (10, 50) includes: a cylinder head; a cam housing (12) attached to an upper surface of the cylinder head; a cam cap (14, 52) attached to an upper surface of the cam housing; a camshaft (16) rotatably supported between the cam housing (12) and the cam cap (14, 52), the camshaft (16) supporting a cam (18); a rocker arm (20) adapted to be pushed through the cam (18); and a valve (22) adapted to be actuated by being pushed by the rocker arm (20); and an oil line (32, 60) integral with the cam cap (14, 52). Lubricating oil is conducted through the oil line (32, 60) to a contact point between the cam (18) and the rocker arm (20).
Description
Technisches GebietTechnical area
Die Erfindung betrifft einen Fahrzeugmotor.The invention relates to a vehicle engine.
Hintergrundbackground
Ein typischer Fahrzeugmotor beinhaltet einen Zylinderkopf, ein Nockengehäuse, eine Nockenkappe, Nockenwellen, Kipphebel und Ventile. Das Nockengehäuse ist an einer Oberseite des Zylinderkopfes befestigt. Die Nockenkappe ist an einer Oberseite des Nockengehäuses befestigt. Die Nockenwellen sind drehbar zwischen dem Nockengehäuse und der Nockenkappe gestützt. Jede Nockenwelle stützt Nocken. Die Nocken schieben die Kipphebel, während die Kipphebel die Ventile derart schieben, dass die Ventile betätigt werden. Ein typischer Fahrzeugmotor beinhaltet des Weiteren eine Spülleitung, durch die Schmieröl zu Kontaktpunkten zwischen den Nocken und den Kipphebeln geleitet wird.A typical vehicle engine includes a cylinder head, a cam housing, a cam cap, camshafts, rocker arms, and valves. The cam housing is attached to an upper side of the cylinder head. The cam cap is attached to an upper side of the cam housing. The camshafts are rotatably supported between the cam housing and the cam cap. Each camshaft supports cams. The cams slide the rocker arms while the rocker arms slide the valves so that the valves are actuated. A typical vehicle engine further includes a purge line through which lubricating oil is directed to contact points between the cams and the rocker arms.
Die Spülleitung ist im Allgemeinen ein separates Bauteil, das an der Nockenkappe oder an einer die Oberseite der Nockenkappe bedeckenden Kopfabdeckung angebracht ist. Dies bedeutet, dass ein von der Nockenkappe oder von der Kopfabdeckung separates Bauteil für die Spülleitung notwendig ist. Die Zahl der Bauteile des Fahrzeugmotors ist entsprechend höher.The purge line is generally a separate component attached to the cam cap or to a head cover covering the top of the cam cap. This means that a separate from the cam cap or the head cover component for the purge line is necessary. The number of components of the vehicle engine is correspondingly higher.
Es besteht daher Bedarf an einem Fahrzeugmotor mit einer geringeren Anzahl von Bauteilen.There is therefore a need for a vehicle engine with a smaller number of components.
ZusammenfassungSummary
Ein Aspekt entsprechend der vorliegenden Erfindung ist ein Fahrzeugmotor, der beinhaltet: einen Zylinderkopf; ein Nockengehäuse, das an einer Oberseite des Zylinderkopfes befestigt ist; eine Nockenkappe, die an einer Oberseite des Nockengehäuses befestigt ist; eine Nockenwelle, die drehbar zwischen dem Nockengehäuse und der Nockenkappe gestützt ist, wobei die Nockenwelle eine Nocke stützt; einen Kipphebel, der dafür ausgelegt ist, durch die Nocke geschoben zu werden; ein Ventil, das dafür ausgelegt ist, dadurch betätigt zu werden, dass es durch den Kipphebel geschoben wird; und eine Ölleitung, die dafür ausgelegt ist, Schmieröl zu einem Kontaktpunkt zwischen der Nocke und dem Kipphebel zu leiten. Die Ölleitung ist integral mit dem Nockengehäuse ausgebildet.An aspect according to the present invention is a vehicle engine including: a cylinder head; a cam housing fixed to an upper surface of the cylinder head; a cam cap fixed to an upper surface of the cam housing; a camshaft rotatably supported between the cam housing and the cam cap, the camshaft supporting a cam; a rocker arm adapted to be pushed by the cam; a valve adapted to be actuated by being pushed by the rocker arm; and an oil passage configured to guide lubricating oil to a contact point between the cam and the rocker arm. The oil passage is formed integrally with the cam housing.
